TRAVERSE-RING.

SPECIFICATION forming part of Letters Patent No. 479,714, dated July 26,1892.

Application filed March 2, 1892.

To all whom it may concern.-

Be it known that I, JAMES W. LESLIE, of Everett, county of Middlesex,State of Massachusetts, have invented an Improvement in Traverse-Rings,of which the following description, in connection with the accompanyingdrawings,is a specification, like letters and figureson the drawingsrepresentinglike parts.

In another application, Serial No. 419,093, filed January 23, 1892, atraverse-ring is shown comprising two separate hollow parts, andfriction-rolls located between the ends of said hollow parts, mounted onaxles, the supports of which are contained in the hollow ends of saidparts. One of the hollow or tubular parts comprises more and the otherless than a half-circle, andsthe supports for the axles of thefriction-rolls contained in the hollow ends of the shorter part of thering are joined by a rod or bar which is therein shown as so constructedas to present a yoke, on the ends of which the axles are formed. Thesupports for the axles are therein shown as solid blocks, suitablyshaped for the purposes intended.

This invention has for its object to reduce the cost of manufacturingthe traverse-ring shown in said application.

In accordance with this invention the supports for the axles are madehollow, being struck up or formed from sheet-brass or some equivalentmaterial, the outer rim or flange of each block having an externalcircumferential groove formed in it, which receives the edges or ends ofthe hollow parts of the ring when said blocks are placed into the hollowends of said parts and said edges are turned inwardly. Each block has acentral hole through it, around which an annular flange is formed,projecting inwardly or in thesame direction as the outer rim or flange.These annular flanges present long and substantial bearings for the endsof the axles upon which the friction-rolls are mounted. The axles areshouldered, so that when the supports are placed thereon they will notabut against and thereby frictionally resist rotation of the rolls. Thesupports for the axles, while preferably contained within the hollowends of the parts of the ring, may be placed upon and thereby Serial No.423,460. (No model.)

receive said ends, and in such event the external circumferentialgrooves in the outer rims or side walls of the supports will be omitted,and the edges of said rims will be turned down over flanges formed onthe adjacent ends of the separate parts of the ring.

Figure 1 shows in vertical section a traverse-ring embodying thisinvention; .Fig. 2, a sectional detail showing a modified form ofsupport for the axle of the friction-roll; Fig. 3, a sectional detail ofanother modification to be referred to, and Fig. 4 an under side view ofa portion of the ring to which the eye is attached.

The ring is composed of two hollow or tubular parts a b, the part acomprising about three-fourths and the part b considerably less thanone-fourth of the complete ring.

Instead of employing a curved or bent rod or bar formed at the ends topresent axles 7c for the friction-rolls, the axles are herein madeseparate and represented at 0. These axles c are shouldered near theends, as at 2 2, to present reduced end portions 0'. The supportsone foreach end of the axle c-are made hollow, and may be struck up or formedof sheet-brass, they being made alike, or substantially so, andpresenting the face or end 3 with an annular rim or flange 4 at theouter edge thereof, and a central hole in said face or end 3, aroundwhich is an annular flange or projection 5, said flanges 4 and 5 beingconcentric. The ends c' of the axle 0 enter the central holes in thesupports and are made of suitablelength to project through and be upset8 5 upon the interior of said supports, thereby connecting the supportsto the axle in such a manner that they cannot easily be separated ordetached therefrom. The faces or ends 3 of the supports abut against theshoulders 2 on the axle, and the friction-roll e, of any suitableconstruction, is placed on the axle between the supports, it being madeof asuitable thickness to turn freely within the space provided for it.The annular projections or 5 flanges 5 present long and substantialbearings for the ends of the axle. The rims or flanges 4 are providedeach with an external circumferential groove G, and the supports havingbeen inserted in the hollow ends of the parts of the ring the edges ofsaid ends are turned inwardly or sunken into said grooves.

I have herein represented the ring as provided with twofriction-rolls,which are adapted to bear upon the upper side of acurtain-pole; but I do not desire to limit my invention to the number ofrolls employed.

Referring to Fig. 4 the hollow or struck-up supports for the axles aremade similar to those shown in Fig. 1, but somewhat larger in diameterto fit over upon the adjacent ends of the parts of the rings instead ofbeing inserted into the hollow ends of said parts, and to secure thesaid supports in place on the ends of said parts, the outer edges of therims or flanges 4 are turned down over upon flanges formed on the endsof said parts. The form shown in Fig. 1 is deemed preferable, as it issomewhat cheaper to construct and more sightly in appearance.

In Fig. 3 I have represented the supports as solid, substantially asshown in the application referred to, but the axle c is shouldered,substantially as represented in Fig. 1, so that the friction-roll emayturn thereon freely or unrestrained. The ring will be provided with asuitable eye.

I claim 1. A traverse-ring composed of the separate parts a b, axle c,shouldered at 2 2 a friction-roll on each axle, and supports for theends of the axle, comprising the end or face 3, with a central holethrough it, an outer flange or rim 4, and an annular projection 5,located at and concentric with the hole, said supports being connectedto the ends of the parts of the ring, substantially as described.

2. A traverse-ring formed to present adjacent end portions, the axle c,shouldered at 2 2, and friction-roll on said axle-supports for the endsof said axle, each comprising the end or face 3, with acentral holethrough it and adapted to abut against the shoulder 2, and also havingan annular rim or flange 4 and a central annular projection 5, saidsupports being connected to the adjacent ends of the ring, substantiallyas described.

3. A traverse-ring composed of separate tubular parts a b, axle-supportssecured to the adjacent ends of said parts, axles c, shouldered at 22,secnred to said axle-supports, the shoulders 2 2 thereof abuttingagainst the ends of said supports to prevent them approaching eachother, and friction-rolls loosely mounted on said shouldered axles,substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JAMES W. LESLIE.
